For questions 1–11, use the Math_achievement.sav file. As part of a large national education study, a researcher is investigating the relationship between math achievement and socioeconomic status. Data have been collected on 999 students enrolled in secondary education. Perform a t test for independent groups for Math by gender.

**What is H₀?**

- The mean of group 0 is the same as the mean of group 1
- The mean of group 0 is not the same as the mean of group 1
- The mean math achievement score for boys is not different than the mean math achievement score for girls
- The mean math achievement score for boys is different than the mean math achievement score for girls
- The mean math achievement score for boys is the same as the mean math achievement score for girls
- The mean math achievement score for boys is not the same as the mean math achievement score for girls
- The mean math achievement score for boys is equal to the mean math achievement score for girls
- The mean math achievement score for boys is not equal to the mean math achievement score for girls
